This invention relates to the broad class of tools and has more specific reference to a novel wrench of a type resembling pliers. Briefly stated, the preferred embodiment 75 of the invention comprises a pair of companionate slidable sections having co-operable' gripping jaws, the stationary section being formed with a rigid handle and the relatively slidable section with a pivoted actuating m lever, oo-acting means being provided between the pivoted end of said lever and said relatively stationary section to provide the requisite take-up action necessary to afford a positive grip on the work.

In carrying the principles of the inventive conception into actual practice, we have discovered a unique arrangement and selection of details carefully proportioned and mechanically co-ordinated to provide a sturdy,

dependable andeflicient tool capable of actions taken on the plane of the lines 4-4 and 5-5 respectively of Figure 1.

Figure 6 is a similar sectional view taken on the line 66 of Figure 2.

Figure 7 is a view in longitudinal section 49 and elevation showing the specific construc tion and arrangement of.

Figures 8 and 9 are perspective views of the essential parts or sections.

Figure 10 is a section taken approximately on the plane of the irregular line 1010 of Figure 1.

Attention is first invited to Figure 9 wherein it will be observed that the relatively fixed or stationary part 11 comprises a shank 12 having an integralgripping han- 1932. Serial no. 622,128.

dle 13 at one end and a laterally directed tooth-equipped jaw 14at the opposite end. Adjacent the point of connection of the handle we provide a plurality of longitudinally spaced depressions forming 'keeper sockets 1 5. N ear the jaw we provide afixed guide loo 16.: v

The relatively adjustable part or section is generally denoted by the numeral 17 and comprises a shank 18 similar to the shank 12 having a laterally directed toothed jaw 19 constructed for co-operation with the firstnamed jaw 14. Incidentally, as seen in Figure 10, the jaws are provided with cutting 7 members 20 forming awirecutter.

The shank 18 is formed at its right hand end with a stirrup or yoke 21 which embraces theshank-l2 asseen in Figures 1 and 7. The 7 extended arm portions of the yoke are apertured and provide attaching ears 22. The actuating lever is distinguished by the numeral 23and hasa right-angularly disposed frustoconical detent 24 which functions as alatch, for co-operation with the keeper sockets and also functions as an end thrust lug in a manner to be hereinafter described. The latch-equipped end of the lever is pivotally attached as at 25 between the cars 22 so as to permit it to assume the position better 8 illustrated in F igure'7 1 v The parts 11 and 17 are assembled in the relationship illustrated in Figure 7, the jaw equipped end of the shank 18. extending through and beyond the guide and retaining M loop 15 and the yoke 21 beingsaddled around the corresponding end portion of the shank 12 Obviously by spreading the handles apart, that is, by'moving the lever 23 away from the handle 13 the latch 24 can be disen gaged from the keeper socket in which it is then arranged, allowing the slidable parts 17 tobe manually adjusted with respecttothe relatively stationary part 11. Then by returning the latch to the nearest keeper socket w it is in position to obtain the final take-up action of clamping the two jaws tightly around the objectwhich may be a pipe, bolt, nut or the like. 1 g

'It is evident from Figure 7 for example that bysquejezing the lever 23 toward the ham dle 13 this exerts a thrusting action of the jaws after the initial adjustment of the jaws latch against the wall of the keeper socket in which it is then arranged, causing the shank 18 to ride longitudinally on the shank 12 to produce this tight clamping or take-up action. Then the tool may be used as any ordinary wrench for object turning purposes.

It is submitted that a toolof this specific type is eflicient in performance, positive and dependable in action, economical and practical, and commercially eligible as a competi- I tive structure in the trade, a noteworthy advance to the prior art to which the invention relates, and otherwise ,capable of fulfilling the requirements of a tool of this class in a gratifying manner. I

' It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be 20' had. Therefore, a more lengthy description is thought unnecessary. While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

We claim:

A wrench of the class described comprising arelatively stationary section in the form of a one-piece body including a longitudinally elongatedshank, said shank being substantially rectangular in cross sectional shape, formed at its outer end with a laterally directed work gripping jaw, and at its opposite end with a suitably shaped longitudinally directed fixed handle, that portion of the shank adjacent the handle connection having its upper flat face bored at longitudinally V spaced points to form a centralized row of depressions constituting spaced keeper sockets, a loop-like guide strap secured to the outer end portion of the shank adjacent said jaw, a relatively movable and adjustable companion section comprising a shank of a shape and proportion corresponding to said firstnamed shank, the second shank having a jaw at its outer end co-operating with the firstnamed jaw with that portion of theshank extending through the aforesaid guide, said second-named shank being formed at its extreme inner end with asubstantially U shaped yoke embracing the corresponding end of the first-named shank and having aperture attaching ears formed at the terminals of the arms of the yoke, and a retaining and jaw setting lever arranged for co-operation with said handle and pivoted at its outer end between said apertured-attaching ears, the pivoted end'of said lever being formed with a right-angularlydisposed integral frusto-conical detent functioning as a latch for selective co-operation with the aforesaid keeper sockets, said latch further functioning as a thrust member in conjunction with the walls of the sockets to provide the final take-up and clamping action for said has been made.

In testimony whereof we afiix our signatures.
